Problems solved by technology

However, satellite signal receivers are generally designed to receive signals from satellites in one satellite system, e.g. the GPS or Galileo, but not both.
Due to the signal differences, receivers of GPS and Galileo signals are not compatible, which is inconvenient.

Abstract

A signal receiver used in a satellite communication system is provided. The signal receiver comprises a first type code generator, a second type code generator, a composite code generator, a correlation module and a determining module. The first type code generator generates a first type code corresponding to a first type signal. The second type code generator generates a second type code corresponding to a second type signal and having a code length N-time longer than that of the first type code. The composite code generator generates a composite code by superimposing N successive first type codes on the second type code. The correlation module correlates the composite code with a cell of a received signal to generate correlation results. The determining module determines a type of the received signal according to correlation results of the composite code with the received signal.

Description

BACKGROUND[0001]1. Technical Field[0002]The present disclosure relates to a satellite communication technology. More particularly, the present disclosure relates to a signal receiver and a signal acquisition method used in a satellite communication system.[0003]2. Description of Related Art[0004]A satellite positioning system (SPS) is a system of satellites that provide autonomous geo-spatial positioning with global coverage. It allows small electronic receivers to determine their location (longitude, latitude, and altitude) to within a few meters using time signals transmitted along a line-of-sight by radio from satellites. Receivers calculate the precise time as well as position, which can be used as a reference for scientific experiments.[0005]Such a SPS satellite typically transmits a signal marked with a repeating pseudo-random noise (PN) code of a set number of chips. For example, a satellite in a constellation of a Global Navigation Satellite System (GNSS) such as GPS or Gali...
